What is a Firestop sealant

There is one important element in firestop materials that makes them different from so many other sealants is the way they behave in a fire.  Of course the “secret sauce” that goes into the product that makes them more expensive than other sealants also.  The key element in many, but not all, firestop products is their capacity to expand when the product is exposed to the heat seen in a fire scenario.  The industry lingo is intumescent.  When looking at the sealants used in firestop they are either used in joint applications so they need to allow for movement, or they are used in through penetrations in which case many applications will require an intumescent product
